銆€銆€Motoring Techonlogy

銆€銆€1.2 million road deaths worldwide occur each year,plus a further 50 million injuries.To reduce car crash rate,much research now is focused on safety and new fuels-though some electric vehicle and biofuel research aims at going faster.

銆€銆€Travelling at speed has always been dangerous.One advanced area of research in motoring safety is the use of digital in-car assistants.They can ensure you don鈥檛 miss important road signs or fall asleep.Most crashes result from human and not mechanical faults.

銆€銆€Some safety developments aim to improve your vision.Radar can spot obstacles in fog,while other technology鈥渟ees through鈥漛ig vehicles blocking your view.

銆€銆€And improvements to seat belts,pedal(鑵宠笍)controls and tyres are making driving smoother and safer.The colour of a car has been found to be linked with safety,as have,less surprisingly,size and shape.

銆€銆€But whatever is in the fuel tank,you don鈥檛 want a thief in the driving seat and there have been many innovations(鍓�(chu脿ng)鏂�).Satellite tracking and remote communications can also come into play if you crash,automatically calling for help.

銆€銆€Accidents cause many traffic jams,but there are more subtle interplays between vehicles that can cause jams even on a clear but busy road.Such jams can be analyzed using statistical tools.Robotic drivers could be programmed to make traffic flow smoothly and will perhaps one day be everyons鈥檚 personal chauffeur(鍙告(j墨)),but their latest efforts suggest that won鈥檛 be soon.

銆€銆€D.Improvements in seat belts,pedal controls and tyres.

銆€銆€4.Satellite tracking and remote communication systems cna be used to

銆€銆€A.reduce oil consumption.

銆€銆€B.remove the obstacles on the road.

銆€銆€C.call for help when one鈥檚 car crashes.

銆€銆€D.help drivers get out of a traffic jam.

銆€銆€5.Which of the following statements is true of robotic drivers?

銆€銆€A.It will take some time before robotic drivers are available.

銆€銆€B.Robotic drivers are not allowed to driveon busy roads.

銆€銆€C.Robotic drivers can never replace human drivers.

銆€銆€D.Robotic drivers are too expensive to use.
